Mat, I'm sorry that was the direction things went. I hope you're doing ok.
Don't send any emails at this time. Really, really think things through and get more input here before you send anything.
You wrote a lot here and I want to reread it a couple of times before I comment. No matter what, please don't spend any time second guessing yourself. You did the best you could in the moment. Sending hugs...
